Actually this is really useful. Whenever a method accepts a `something` or an `array of somethings` you can use the splat operator to make it an array if it's not already. Now you can operate on it as an array.

~~~ ruby
def initialize( something )

   @something = *something

end
~~~

If it didn't do that, you would have to write:

~~~ ruby
@something = something.kind_of?( Array ) ? something : [something] 
~~~
